Suggestion:

    Something may be causing something.

Counter Argument:

    There's no proof of that.

Counter Counter Argument:

    Ah, but is there any evidence that 'Something' is *not* causing it.

No, you see, that's not how logic works. You provide evidence for something; not the absence of evidence for it not happening.

There's even a name for it. It's called: argumentum ad ignorantiam (guess what that translates as), also known as an appeal to ignorance.

Any platform can and will be "politicized." Mediums that allow unbridled communication between humans are always political to a varying degree. "Politics" is really just a word for structured disagreement, it happens and is happening everywhere.

And just to be clear, "prove they're not leaving" is not a great argument. I mean I guess they might be? But $66m dollars is a lot of money. They'd have to lose over a million paying customers to lose that much from people switching away. This is a simple calculation that returns a boolean, there are either a significant number of paying customers leaving such that it impacts on the scale of millions of dollars (and we're talking about a product that is $7/month for individuals here, that's a lot of $7 subs) or there aren't.

What do you think the ballpark is for paying customers irritated enough by that thread's existence that they leave the service altogether? I honestly don't know, I wouldn't know where to begin quantifying.
